Extendable Ceramic Briquette Holder Flame Tamer made from vitreous enamel coated steel. Will suit most BBQ brands with flame tamer depths between 385mm (min) & 485mm (max.). This flame tamer enables you to use ceramic briquettes, which causes juices and fat to evaporate, but also enables the even distribution of heat from the burners to be radiated to the cooking grill above. (Ceramic Briquettes not included).
